Industrial aluminium profile is the material that is commonly used in many industries. But in the process of production, is not so easy, often because of various factors, the aluminum is not so perfect. Among them, aluminum easy to oxidation, it is a headache problem. In the face of such situation, the staff should do?

(1). Aluminum aging method according to climate condition. In the sunny summer, it can be exposed to the sun, in the rain or in winter, it can be baked in the oven. Process condition is: temperature 40 ~ 50 ℃, keep 10-15 minutes.

(2) wash with hot water. Hot water washing is designed to make film aging. However, should strictly control the temperature and time. When the water temperature is too high, thin film layer and the color becomes shallow. When industrial aluminum processing time is too long, may be the similar problems. The right temperature and time is: the temperature of 40 and 50 ℃, time of 0.5 to 1 minute.

(3) dry. The most natural drying and drying. Filled with hot water in the workpiece on the shelf, make work direction along a straight line on the surface of the free water flows downwards. Inflow Angle under the water with a towel to absorb, in this way, the color of the dry film is not affected, looks very natural.

(4) the rework of unqualified parts. It should be selected before drying and aging process. Due to drying and aging, thin film layer is difficult to remove and will affect industrial aluminium profile surface roughness. In this process have been discussed this problem. Through a variety of methods, found the following method is effective, method is simple, does not affect the workpiece surface quality.

Specific process is as follows: first of all, will not be qualified industrial aluminum clamp on the aluminum. In anodic oxidation on the jig, then according to the method of anodic oxidation of aluminum in sulfuric acid solution for anodic oxidation 2 to 3 minutes, until soft and thin film layer falls off, then slightly alkaline cleaning and nitrate lit to anodic oxidation treatment again.
